Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.

replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump

the probem is probably in the injector assembly whichis under the intake plenum.after removing it you will se the plastic tubes and ijector popit valves unlike actual individual injectors.this whole contraption must be replaced as an assembly.you can get repair manuals from this site or go to you library.it may actually be flooding as these had problems with leaking fuel pressure regulators which i think are also only part of the whole assembly.
